AI Technical Summary
The bathroom system design of existing RVs has problems such as small water storage, slow heating speed, and large water consumption, which leads to unstable water temperature when users bathe in RVs, which cannot meet the needs of long-term showers, and the gray water tank is easily stored and caused discharge. difficulty.
Design a RV circulation shower tray that integrates heater, water pump, water level sensor and temperature sensor, providing two usage modes: water mixing mode and circulation mode. In the circulation mode, the heater automatically heats when the water temperature drops, the water level sensor prevents dry burning, and automatically turns off after the circulating water temperature reaches the set temperature. The heater realizes stable control of the water temperature and turns off the heater when the water level is lower than the set value. .
Effectively save water, ensure the water temperature stability of long-term showers, reduce the generation of gray water, and improve the user's bathing experience in RVs.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of recreational vehicles, in particular to a circulating shower tray for recreational vehicles. Background Art
[0002] With the development of RVs and the promotion of RV self-media people in recent years, the RV market is very hot and the demand for RVs continues to rise. It is regrettable that there are many unreasonable designs of RVs on the market, and the products are seriously homogenized, resulting in poor user experience.
[0003] The bathroom system of RV is a module that many RV practitioners and RV companies tend to ignore. Most RV users choose to compromise and make do due to the various shortcomings of the RV bathroom module, which reduces the user's happiness in living in the RV. Specifically, there are the following points: 1; the water storage capacity of the water heater is small, and the hot water is used up after just a short shower; 2; the heating power of the water heater is small, and the heating speed cannot keep up with the water usage speed. The water temperature drops before the shower is halfway done; 3; the water consumption is large, and a simple shower requires at least 40L of water, which will cause water anxiety. Most RV users will choose to take a shower in the RV camp; 4; due to the large water consumption, the gray water tank is easily filled with bath water. In places that are not suitable for discharging gray water, there will be problems with gray water backflow or bath water cannot be drained. Utility Model Content
[0004] The utility model provides a circulating shower tray for a motorhome
[0005] The main purpose is to solve the problems of unreasonable shower module design, small hot water storage, slow heating speed and large water consumption for bathing in the existing RV market.
[0006] To solve the above problems, the utility model adopts the following design:
[0007] A circulating shower tray for an RV, characterized by comprising: a water collecting tray, a heater and a water pump disposed inside the described water collecting tray, and a drain outlet at the lowest point of the described water collecting tray, a shower head disposed above the described water collecting tray, a selection switch and a water mixing switch disposed between the described shower head and the described water collecting tray, the described selection switch being connected to a circulating water pipe and a water mixing pipe, the described water mixing switch being connected to a cold water pipe and a hot water pipe, a water level sensor being disposed on the upper edge of the described heater, a water pump outlet being disposed above the described water pump and a water pump inlet being disposed below the described water pump, a temperature sensor being disposed on the edge of the described water pump outlet, and a removable filter being disposed inside the described water pump inlet.
[0008] There are two usage modes in total;
[0009] The first mode: the mode without circulation function. The order of use is to first adjust the selection switch to the mixing water mode and the shower starts to discharge water. At this time, adjust the water temperature to the appropriate temperature through the mixing water switch and you can take a shower.
[0010] The second type: use the circulation function mode. Before starting the first mode or during use, close the drain outlet described. When the water level in the shower tray exceeds the water inlet of the water pump, you can adjust the selection switch to the circulation water mode, and then turn on the water pump. When the circulating water temperature drops below the set temperature, and the water level sensor located above the heater contacts the water, the heater starts to heat the circulating water. When the set temperature is reached, the heater automatically turns off, or when the water level is lower than the water level sensor, the heater automatically turns off to prevent dry burning. The second circulation mode can save water while meeting the requirements of long showers.
[0011] The advantages mentioned above are obvious. They solve the problems of large water consumption in showering, large amount of gray water, unstable water temperature, and inability to meet long-term showering needs. The RV shower module of the utility model is a disruptive innovation and will greatly improve the user satisfaction of RVs. BRIEF DESCRIPTION OF THE DRAWINGS
